So I have recently been looking at posts from 2019 on this forum on how to make a CVT transmission 3 hours later, I made a car made in automation from a regular auto to a CVT It's been working great on the grid map But as soon as I started testing it out on rougher roads and realistic road conditions the "CVT" would bug out, revs would jump up and down, the car would shake, it wouldn't accelerate because of the "power" going up and down, as soon as you let off the throttle it would immediately start decelerating with good amount of force All of this would happen only over 62mph/100kmh I've uploaded a video of that happening I have no idea how to fix this So If anyone that had the some experience on this and any tips on how I could fix this, I would appreciate it
